Hi, This is my first ever forum post. I really need some help with understanding how to setup a GWT 2.0 Hibernate3 project. I understand the GWT RPC mechanism and the problems with serializing Hibernate POJOs. I would prefer to use DTO's rather than Gilead or Dozer. So far, I have a Hibernate Project built with Maven2 in Eclipse using the m2eclipse plugin and the HibernateTools plugin for Eclipse. I also have a GWT 2.0 project built with the GWT plugin for Eclipse. I'm using MySql as the RDBMS. What I don't understand is how to setup, configure, and deploy the two projects in such a way that they can communicate with each other.
Let's say with the above setup, I'm trying to persist a Person object that has only an id, and a name as fields. In my Hibernate project, I would create a Person.hbm.xml Hibernate mapping document, and then generate the corresponding Hibernate Java POJO and MySql table. Then, in my GWT project, I would create a serializable PersonDTO.java class that can be sent 'across the wire' to and from the server via GWT RPC. Then, for simplicity's sake, let's say that in the client package of my GWT project I create a CreatePersonService.java interface and a CreatePersonServiceAsync.java interface with one method, void createPerson(). I would then need a CreatePersonServiceImp.java class on the server side that implements createPerson(). Fine, but here's where I get confused. If the createPersonServiceImp.java class is going to transform a PersonDTO.java class into its Hibernate POJO equivalent, then it needs to utilize classes from both my GWT Eclipse project and Hibernate Eclipse project. So which project do I put it in? It needs to have access to GWT classes like PersonDTO, AsyncCallback and other RPC classes. It also needs access to Hibernate classes like SessionFactory, Transaction, etc. So it needs to have access to my GWT jars and Hibernate jars which are in two separate projects. How do do I link them so that CreatePersonServiceImp.java has access to all the libraries it needs. Finally, how do I correctly merge both of these projects into one WAR file for deploying onto a server? Or am I way off track? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group. To post to this group, send email to [email protected].
